Conditions for Setting the DTC

WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The powertrain control module (PCM) has not established communications with the body control module (BCM) and has not received a valid password before the fuel disable decision point was reached.
